When measuring the imitation eyes, check that
there is no dust or stain on them.
Check that the lens in the measurement window on the
patient’s side is clean and free of damage. If the lens is
contaminated or damaged, measurement may not be

model eyes provided in the package in order to inspect
these points. (Refer to “5.3.1 Calibration checks.”)

starting the inspection for the day.
Turn off the instrument and relevant accessories, and
unplug the instrument and plugs of all the AC-Adapters
before conducting maintenance and inspection with the
outer cover of the accessory opened.
